Application of Signal Enhancement Method Based on Time-Frequency Peak Filtering to Seismic Data Processing
Wei Pan · Journal of Jilin University · 2007
It is essential to seismic data processing that event is recovered clearly from noisy seismic data without losing energy of the signal.The timefrequency peak filtering(TFPF) based on pseudo Wigner-Ville distribution(WVD) was applied to process common shot point seismic record to eliminate the noise.This method achieved an unbiased estimation of the complex seismic record.The efficient information in seismic data was enhanced,and the random noise in the seismic data was removed,and the seismic event was recovered effectively.Compared the results from practical seismic record before and after TFPF processing,the effective information in seismic data was enhanced evidently,and the continuity of event was improved simultaneously.
